| # QNX hints |
| # |
| # Most of the hints in this file are for QNX4, which needed |
| # more help. The QNX6 hints are located toward the bottom. |
| # |
| # perl-5.7.3 passes all tests under QNX4.24G |
| # Watcom 10.6 with Beta/970211.wcc.update.tar.F |
| # socket3r.lib Nov21 1996. |
| # perl-5.7.3 fails 2 known tests under QNX6.1.0 |
| # |
| # perl-5.10.0-tobe compiles with Watcom C 10.6 |
| # and QNX 4.25 patch G w/TCPSDK installed |
| # Some tests still fail, mostly to do with dynamic/static |
| # or unsupported features in QNX. |
| # |
| ## As with many unix ports, this one depends on a few "standard" |
| # unix utilities which are not necessarily standard for QNX4. |
| # |
| # /bin/sh This is used heavily by Configure and then by |
| # perl itself. QNX4's version is fine, but Configure |
| # will choke on the 16-bit version, so if you are |
| # running QNX 4.22, link /bin/sh to /bin32/ksh |
| # ar This is the standard unix library builder. |
| # We use wlib. With Watcom 10.6, when wlib is |
| # linked as "ar", it behaves like ar and all is |
| # fine. Under 9.5, a cover is required. One is |
| # included in ../qnx |
| # nm This is used (optionally) by configure to list |
| # the contents of libraries. I will generate |
| # a cover function on the fly in the UU directory. |
| # cpp Configure and perl need a way to invoke a C |
| # preprocessor. I have created a simple cover |
| # for cc which does the right thing. Without this, |
| # Configure will create its own wrapper which works, |
| # but it doesn't handle some of the command line arguments |
| # that perl will throw at it. |
| # make You really need GNU make to compile this. GNU make |
| # ships by default with QNX 4.23, but you can get it |
| # from quics for earlier versions. |
| #---------------------------------------------------------------- |
| # Outstanding Issues for QNX4: |
| # There is no support for dynamically linked libraries in |
| # QNX4. |
| # |
| # If you wish to compile with the Socket extension, you need |
| # to have the TCP/IP toolkit, and you need to make sure that |
| # -lsocket locates the correct copy of socket3r.lib. Beware |
| # that the Watcom compiler ships with a stub version of |
| # socket3r.lib which has very little functionality. Also |
| # beware the order in which wlink searches directories for |
| # libraries. You may have /usr/lib/socket3r.lib pointing to |
| # the correct library, but wlink may pick up |
| # /usr/watcom/10.6/usr/lib/socket3r.lib instead. Make sure |
| # they both point to the correct library, that is, |
| # /usr/tcptk/current/usr/lib/socket3r.lib. |
| # |
| # dist/Cwd/Cwd.t will complain if `pwd` and cwd don't give |
| # the same results. cwd calls `fullpath -t`, so if you |
| # cd `fullpath -t` before running the test, it will |
| # pass. |
| # |
| # lib/File/Find/taint.t will complain if '.' is in your |
| # PATH. The PATH test is triggered because cwd calls |
| # `fullpath -t`. |
| # |
| # ext/IO/lib/IO/t/io_sock.t: Subtest 14 is skipped due to |
| # the fact that the functionality to read back the non-blocking |
| # status of a socket is not implemented in QNX's TCP/IP. This |
| # has been reported to QNX and it may work with later versions |
| # of TCP/IP. |
| # |
| # Older issues: |
| # lib/posix.t test failed on test 17 because acos(1) != 0. |
| # Resolved in 970211 Beta |
| # lib/io_udp.t test hangs because of a bug in getsockname(). |
| # Fixed in latest BETA socket3r.lib |
| #---------------------------------------------------------------- |
| # Outstanding Issues for QNX6: |
| # The following tests are still failing as of 5.7.3: |
| # |
| # op/sprintf.........................FAILED at test 91 |
| # lib/Benchmark......................FAILED at test 26 |
| # |
| # This is due to a bug in the C library's printf routine. |
| # printf("'%e'", 0. ) produces '0.000000e+0', but ANSI requires |
| # '0.000000e+00'. QNX has acknowledged the bug and it should be |
| # fixed in 6.2.0. |
